In biological taxonomy, a domain (Latin: regio) is the highest taxonomic rank of organisms in the three-domain system of taxonomy designed by Carl Woese, an American microbiologist and biophysicist. According to the Woese system, introduced in 1990, the tree of life (biology) consists of three domains: Archaea (a term which Woese created), Bacteria, and Eukarya.
